ASH-SIFTER.

Application filed January 23, 1920.

To all whom it may conhern:

Be it known that I, HARRY Roznivsnn, a citizen of Poland, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful 11nprovements in Ash-Sifters, of which the following is a specification.

This invention relates to certain new and useful improvements in ash sifters, and the primary object of the invention is to provide an ash sifter of extremely eflicient and durable construction so as to effectively separate ashes from coal in the Well known and desirable manner.

The invention embodies broadly a hopper for reception of the ashes to be sifted, and an open-ended rotary sifting member tiltable for filling and capable of being lowered and rotated for sifting of the finer particles therethrough into a suitable receptacle, a slide being provided for opening the open end of the rotary siftin member for permitting the coal to be de ivered into a separate receptacle.

The invention is illustrated to one em bodiment thereof in the accompanying drawings wherein like reference characters indicate corresponding parts throughout the several views,

Figure 1 is a longitudinal substantially central vertical sectional view of an ash siftcr constructed in accordance with the present invention,

Fig. 2 is a vertical sectional view thereof taken substantially upon line IIII of Fig. 1,

Fig. 3 is a horizontal sectional view taken upon line IIIIII of Fig. 1 with parts removed,

Fig. 4 is a similar view taken upon line IV-JV of Fig. 1, r

Fig. 5 is a view similar to Fig. 4 taken upon line VV of Fig. 1,

Fig. 6 is a horizontal sectional view taken sublstantially upon line VI-VI of Fig. 2, an

Fig. 7 is a sectional fragmentary view illustrating the slide utilized for closing the open end ofthe rotary sifting member and the guide within which the shaft of said siting member is shifted.

rectangular form in horizontal section and supported upon suitable legs 6 which are provided with casters 7 at their lower ends. The upper end of the casing 5 is provided with a hinged cover or closure 8, and a hopper 9 is provided in the upper portion of the casing 5 directly beneath the cover 8. The hopper 9 is provided with a contracted outlet at its bottom portion, and this outlet is closed or opened as desired by means of a slide or gate 10 which is guided in suitable guides 11 which project rcarwardly from the bottom portion of the hopper 9 in a substantially horizontal position. A handle 12 is carried'by the slide 10 and extended rearwardly through an aperture 13 in the rear wall of the casing 5 so that a person may grasp said handle from the exterior of the casing for slidin the gate 10 to open the bottom outlet of die hopper 9 or to close the same at will.

A shaft His normally disposed in a slight forwardly inclined position beneath the hopper 9 and is mounted in the rear wall of the casing 5 as at 15 so that the shaft is capable of being swung upwardly and downwardly as well as being capable of being rotated upon proper actuation of the handle 16 which is formed upon the rear end of said shaft 14 exteriorly of the casing 5.

The forward end of the shaft 14 is received within a vertical elongated guide 17 which is of arcuate form and rigidly secured at its ends as at 18 to the front wall of the casing 5. The lower end of the guide 17 is disposed so as to support the forward end of the shaft 14 for rotation at a slight forward incline and is extended upwardly where its upper end terminates a short distance beneath the bottom outlet of theho per 9. The shaft 14 is part of a rotary si tin'g drum, the drum proper being formed by a'screen member 19 of substantially tubular form and having an open forward end and a closed rear end, the screen 19 being supported in concentric relation to and surroundin the shaft 14' by means of a frame 20 an spiders 21.

A slide 22 is movable through a slot 23 provided in one side wall of the casing 5 so as to be ,moved inwardly for closing the forwardopenend of the sc, p g-1pm.; s n -Ri i i 'ngvii pt evtiiawhln a"i6n iiii n2, llit subw stantially centrally and inwardly from its forward end so. as to accommodate the shaft 16L. The slide 2:2 is provided with a handle 25 positioned eXteriorly of the casing so that said slide may be manually moved inwardly or outwardly for closing or opening, as desired, the forward end of the drum 19.

An inclined chute 26 is rigidly mounted upon the front wall of the casing 5 and extends inwardly through an opening 27 provided in said front wall so that the inner end of the chute 2G is disposed beneath the open end of the drum 19. The lower end of the chute 26 is provided with a hook 28 adapted to receive the hail of a coal hod or other receptacle in the usual manner.

The bottom of the casing 5 is closed by means of a gate 29 which is hinged at its rear edge as at 30 adjacent to the rear Wall of the casing 5 for vertical swinging movement, said gate 29 being held in its upper or closed position against the abutment 31 which is provided upon the lower edge of the front wall of the casing 5 beneath the chute 26, by means of a pair of strong leaf springs 32 whose rear ends are rigidly attached to the casing as at 33 rearwardly of the pivot 30, and whose forward ends bear against the under face of the gate 29 as best shown in Fig. l. The gate 29 is preferably inclined and is provided with a handle 34: which may be lifted upwardly for the opening of the gate.

In operation, the cover 8 is raised for opening the upper portion of the casing so that the material to be sifted may dumped into the hopper 9 and the drum 19 is then tilted upwardly by pressing downwardly upon the handle 16 so that the open forward end of said drum is disposed to receive the contents of the hopper 9 as indicated by dotted lines in Fig. 1. hen the drum has been filled or partially filled with the material, the same. is allowed to move downwardly to its normal full line position of Fig. 1 and the slide 22 is then moved inwardly so as to close the open forward end of the drum 19. The operator then turns the handle 16 for imparting rotation to the drum I9 and the finer.particles are sifted through said drum in the usual manner onto the gate 29. A suitable receptacle may be placed between the front legs 6 of the Sifter for receiving the finer sifted particles when the same are allowed to slide downwardly on the gate 29 by the opening of said gate through lifting the handle 34. The slide 22 is then withdrawn to substantially the position thereof as shown in Fig. 7, whereupon thelarger particles are caused to move forwe rdly onto the chute 26 upon further rotation of the drum. the said larger particles being deposited in the receptacle which is hung upon the hook 28.

Q From the foregoing description, it is belicved that the corn-dructimr and operation of the present invention will be readily understood.
